php regex match exact number 10 in an URL

Question

I have an URI like

myurl-c-10_550_05.html

I would like to match any URI containing the exact number 10 anywhere , like :

myurl-c-10_550_05.html
myurl-c-550_10_05.html
myurl-c-550_05_10.html
myurl-c-550_10.html
myurl-c-10.html

but not 100 or 1000 like

myurl-c-100_550_05.html  << Wrong

What I tried and working for the figure 10 or 100 or 1000 is :

preg_match("/-c-(?:[0-9_]+|)(10)(?:[0-9_]+|)/",$baseuri) 

But I can't get the fixed 10 figure even whith this other regex :

preg_match("/-c-(?:[0-9_]+|)(^10$)(?:[0-9_]+|)/",$baseuri) 

I've spent nearly 2 hours on stackoverflow , reading a lot, trying a lot with this cool tool :

EDITED : this regex should also check there is a -c- in the uri followed by some digits and undersocre or not and ending with a point.

not working : myurl-i-10_gasp.html

Can someone help me ? Thanks !

Answer 1

Try one of these:

"/-c-(\d+_)*10\D/"
"/-c-(\d+_)*10(?!\d)/"

Answer 2

The solution with the help of Toto :

-c-(?:[0-9_]+|)(?<!\d)10(?!\d)
